A member asked:
Can any doc tell me what's the difference between thyroxine, thyrocalcitonin and triiodothyronine?
A doctor has provided 1 answer
Yes: Thyroxine also known as T4 is the main product of the thyroid gland. Triiodothyronine or t3 (liothyronine) is also a product of the thyroid but most of it comes from the conversion of T4 in the human tissues by the enzyme deiodinase. T3 (liothyronine) is the active and most potent form of thyroid hormone. Thyrocalcitonin or just calcitonin is unrelated to the above two, comes from the c-cells, and affects the calcium level.
